Programmable Logic Devices (PLDs)

Programmable logic devices (PLDs) and parts function as the brains behind most technological advances
By Deneatra Harmon Programmable logic devices are also referred to as programmable logic controls or programmable logic controllers. A programmable logic controller (PLC) consists of small microcomputers or electronic parts that software designers can use to program machinery and computer-related applications. Programmable logic controller programming works in materials handling, food packaging and processing, machining and batch process controls. Data management systems and local area networks also rely on programmable logic controllers.
 

Programmable logic control tools are incorporated into office or industrial functions such as mathematical calculations, hardware interfacing, timing and control, data communication, signal processing, and data entry and display. Software designers then use programmable logic devices to test in graphic calculators, DVD players, GPS navigation systems, computer network routers and DSL modems. Programmable logic devices (PLDs) have real-time capabilities that allow electronics and other products to work immediately upon reprogramming. Programmable logic devices can be reprogrammed as often as necessary because software designers use tools that feature rewritable memory technology. A programmable logic device is small enough to place next to other microprocessing machinery for easy accessibility.

• Programmable logic devices are inexpensive to produce and program. They can also operate in temperatures ranging from 0 to 50 degrees F.
• Programmable logic controllers perform functions such as logic, sequencing, mathematical, counting, digital and analog inputs and outputs to monitor speed, temperature or pressure. Assembly lines and robots are also controlled by PLC programmable logic controllers.
• Electronics and other automated products can be reprogrammed remotely through the Internet or from a control center that works with programmable logic devices, even after the items have been shipped to a customer.
